Wiretrustee SATA is a Raspberry Pi Compute Module 4 (CM4) carrier board for DIY network attached storage (NAS). It is the first such board to directly transfer data via the native CM4 PCIe interface, and thus avoids unstable USB-to-SATA connections.
Wiretrustee SATA features four SATA ports, one gigabit Ethernet port, and a small form factor (100 x 100 mm), making it possible to build a tiny home NAS. It supports 2.5" and 3.5" drives, both SDDs and HDDs. Whereas 2.5" drives can be plugged in directly, 3.5" drives require additional extension cables.
In addition to a fully assembled and tested board, we plan to offer DIY kits for building your own complete NAS.
Wiretrustee SATA supports all the Compute Module 4 variants thanks to a microSD card slot (for CM4 light) and a firmware flashing mode via the top-side USB 2.0 port (for CM4 with eMMC).
Wiretrustee SATA board has been verified to work with Raspberry Pi OS with SATA drivers enabled in a cross-compiled kernel. All the necessary installation instructions and scripts (including RAID setup), as well as board schematics and PCB layout, will be published on our website.
"Wiretrustee has designed an ultra-compact x4 SATA Raspberry Pi CM4 carrier board with up to 220MB/s throughput for NAS applications."
"The good news is the board is now open-source hardware with all resources shared publicly including the Allegro schematics and PCB layout, Gerber files, 3D models for the heatsink, and case designs for 2.5-inch or 3.5-inch drives. "
